DDEInitiate Method
Opens a DDE channel to an application.
expression.DDEInitiate(App, Topic)
expression Optional. An expression that returns an Application object.
App Required String. The application name.
Topic Required String. Describes something in the application to which you're opening a channel — usually a document of that application.
Remarks
If successful, the DDEInitiate method returns the number of the open channel. All subsequent DDE functions use this number to specify the channel.
Example
This example opens a channel to Word, opens the Word document Formletr.doc, and then sends the FilePrint command to WordBasic.
channelNumber = Application.DDEInitiate( _
app:="WinWord", _
topic:="C:\WINWORD\FORMLETR.DOC")
Application.DDEExecute channelNumber, "[FILEPRINT]"
Application.DDETerminate channelNumber
